It is a very labor intensive process in which you basically make designs with wax on an egg, then dye the egg in different colors after each wax design layer is made. When your egg is done is looks black until you melt off the wax as shown in the photo below.
Granted it takes forever and is truly an art but still a fun tradition to remember.
Traditionally they look like the designs above, but new modern colors and designs are popular and full of inspirational color combinations.
